Get rid of parenthesis, this is addition it doesn't matter how you add it will give you the same answer
3/8+2/3+1/3
3/8+3/3
3/8+1
3/8+8/8
11/8→1 3/8→1.375
Note that a squared pyramid has a square base & 4 equal triangles.
To find the lateral the lateral area you calculate the area of the 4 equal triangles and to find the surface area (total Area) you add the area of the base:
Area of each triangle = side (5) x slant (9) and you divide by 2
==>Aera of 1 triangle = (9x5)/2 = 45/2 & for the 4 triangles
Lateral area = (45/2) x 4 = 90 in²
Now the base area (square) = 5 x 5= 25 in²
so the surface area = 90+25 = 115 in² (answer a)
16 lesson. The equation is 240÷15=16
And like I said 240÷15 is 16
So here I hope it helped You

Answer:
X=20
Step-by-step explanation:
(0.5 liter/bottle) x (6 bottles/pack) = 3 liters/pack
(10 days) x (1.5 liter/day) / (3 liter/pack) = <u>5 packs</u>
